Problem statement: Two identical cyclists ride past each other with constant velocities Va and Vb, which are close to the speed of light. Can it be that cyclist A perceives cyclist B as shorter or longer that cyclist B percieves cyclist A ? Or simply La is NOT equal to Lb ? (La-length of cyclist A as seen by cyclist B, Lb -length of cyclist B as seen by cyclist A). Relevant formulas: Relative speed V = Va+Vb/(1+(Va*Vb/c^2)) Relative length l = lo * square root from 1-(V/c)^2 Conclusion: The V from the second equasion is equal for both cyclists, since addition and multiplication are alternate. lo is also equal. So there is no difference in the way cyclists A and B see each other. Is this conclusion right?
